Investment Thesis
Affirm is a balance-sheet lender masquerading as a FinTech platform. Unlike Klarna and other BNPL peers that rely primarily on merchant fees, Affirm generates roughly half its revenue from high-APR interest income.
This is scale without quality and growth without durability. Expansion has been driven by aggressive credit extension to weak-credit borrowers and by extracting more borrowing from repeat users who are increasingly financing necessities rather than discretionary purchases. When a business shifts from financing Pelotons to installment plans for groceries, it is no longer "democratizing credit" but rather levering the financially fragile.

Critical Risk Metrics

Effective Leverage
Once off-balance-sheet loans with retained credit exposure are included. Peers average ~7x but with better reserves.
~1%
Reserves / GMV
Woefully thin cushion. Reserves cover only ~2% of retained risk vs. 8%+ at peer consumer lenders.

Repeat Users
Growth depends on stacking more loans onto same borrowers. A saturation signal, not expansion.

Kerrisdale Conclusion
The Bill Is Coming Due
▼ Short Position
Affirm has been dining out on easy credit and full employment. The company is a balance-sheet lender that has only ever been tested in the most forgiving credit environment imaginable. Today, those tailwinds are reversing. Leverage is higher, retained credit exposure is larger, and reliance on interest income is at a peak. With reserves covering roughly 2% of retained risk and ~1% of GMV, there is no buffer for normalization. When credit losses rise, earnings will not fade gradually—they will snap back into losses as reserves are rebuilt and capital comes under pressure. The stock is priced for sustained growth and stability. The business is built for neither.
